Resveratrol is an antioxidant polyphenol with great promise for supporting healthy metabolism, normal insulin sensitivity, and optimal blood flow — all of which may have cardiovascular, brain, and healthy aging benefits.*
However, resveratrol, while reasonably well-absorbed, has a very short half-life. Because it does not stay in the bloodstream very long, its benefits can be difficult to reap. After oral administration, the amount of free resveratrol in plasma accounts for less than 2% of total resveratrol. In some instances, it isn’t even detected.
MicroActive® Resveratrol was developed to address this issue through a micronized, sustained-release technology that allows for better absorption and retention.
• 12-hours sustained release
• Increased systemic exposure
• Effective at low doses
• 2.5x more bioavailability than standard resveratrol
MicroActive® Resveratrol was compared with 99% resveratrol powder in a dissolution study that approximated transport through both the gastric and intestinal environments. Compared with resveratrol powder, MicroActive® Resveratrol dissolved slowly and demonstrated sustained release over a longer period. The resveratrol powder showed complete dissolution (100%) in 4 hours. The MicroActive® formula showed sustained release over 12 hours, with 97% of the dose released.
In a pilot study, resveratrol powder showed a rapid absorption with a sharp peak at Tmax of 2 hours postdose. After 2 hours, the plasma levels of total resveratrol declined rapidly with a small increase at 9 hours. MicroActive® resveratol also showed a Tmax at 2 hours and lower Cmax (max. concentration at Tmax) with a broader peak and higher plasma levels compared with the control. Sustained release continued for > 9 hours. This implies that while 98% resveratrol powder is rapidly absorbed and excreted, MicroActive® resveratrol continues to remain in circulation for a long time.
